摘要

Greenhouse ( 1 ) provided with a roof element ( 2 ) having a multiplicity of transverse ribs ( 12, 13, 14, 15 ) or pyramids uniformly distributed over the roof element. The roof element can be constructed double-walled as a hollow-core sheet from transparent plastic and can comprise a base sheet with the rib-shaped or pyramid-shaped roof surfaces fixed thereon. The light yield in a horticultural greenhouse can be increased by the roof elements.
